Can Distance Sampling be Used to Estimate the Abundance of Mountain Ungulates? A Comparison of Distance Sampling and Double‐Observer Survey Methods 距离样线法能用于估算山地有蹄类动物的数量吗?——距离样线法与双观察者法的比较

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 302-309, September 2025.
We discussed the key assumptions of Distance sampling that were considered hard to meet in mountainous terrains and potential solutions for them. Our survey yielded comparable estimates from distance sampling and double‐observer survey, although the confidence interval from distance sampling was broader.

Diversity and Activity Pattern of Terrestrial Mammal Species in Serra do Amolar, Brazilian Pantanal 巴西潘塔纳尔湿地阿莫拉尔山脉陆生哺乳动物物种的多样性及活动模式

open access: yesWildlife Letters, Volume 3, Issue 2, Page 56-63, June 2025.
The Serra do Amolar, located in the Brazilian Pantanal, is a crucial but understudied area for biodiversity conservation. Through camera traps, we recorded 29 mammal species, including three rodent species documented for the first time in the area: Cavia aperea, Cuniculus paca, and Holochilus chacarius.

Comparative efficacy of selenoureido carbonic anhydrase inhibitors and azole antifungal drugs against clinical isolates of Malassezia pachydermatis

open access: yesVeterinary Dermatology, Volume 36, Issue 3, Page 302-313, June 2025.
Background – Malassezia pachydermatis (MP) is implicated in severe dermatitis and otitis externa (OE) of companion animals and recently gained attention for its increasing resistance to azole compounds. For this reason, developing novel therapeutic strategies is of great interest. In a previous work, we used reference yeast isolates to evaluate several

GIS隔离开关气室电场模拟与绝缘故障分析

open access: yesGaoya dianqi, 2020
隔离开关广泛应用于气体绝缘开关设备(GIS)中,文中采用三维有限元电场分析软件,建立了GIS隔离开关气室的三维电场仿真模型,计算了GIS隔离开关气室内各部件的电场分布,研究了金属异物对隔离开关气室内部SF6间隙电场分布的影响规律,发现金属异物的存在引起隔离开关动触头屏蔽罩附近场强发生明显畸变,可能会导致GIS隔离开关气室绝缘故障。文中研究通过电场模拟手段,分析了金属异物对GIS隔离开关气室内部电场分布的影响,为今后GIS类似故障的处理分析提供借鉴与参考。

The potential influence of genome‐wide adaptive divergence on conservation translocation outcome in an isolated greater sage‐grouse population

open access: yesConservation Biology, Volume 38, Issue 4, August 2024.
Abstract Conservation translocations are an important conservation tool commonly employed to augment declining or reestablish extirpated populations. One goal of augmentation is to increase genetic diversity and reduce the risk of inbreeding depression (i.e., genetic rescue).

兩柱式户外隔离开关的結构研究

open access: yesGaoya dianqi, 1959
目前电器工业中有逐漸以生产兩柱式戶外隔离开关来代替三柱式戶外隔离开关的趋势,西欧国家已紛纷生产南柱式隔离开关;捷克、波蘭等东欧人民民主国家也已生产兩柱式的隔离开关,苏联近年也正在逐步以兩柱式代替三柱式的,我国电力部門对这种新型的隔离开关也非常注意。本文就个人所見对兩柱式和三柱式隔离开关以及V型隔离开关作一分析此較。

Understanding teacher professional commitment from a positive psychology perspective: A case from Myanmar's Chinese language teachers

open access: yesThe Modern Language Journal, Volume 108, Issue 1, Page 222-242, Spring 2024.
Abstract In response to the issue of Chinese language teacher attrition in Myanmar, this study aimed to examine the professional commitment of these teachers, with a focus on how their commitment is constructed and shaped within the local context. The study adopted a theoretical lens of positive psychology and utilized a hermeneutic phenomenological ...

一种光隔离器

open access: yes, 2011
本发明提供了一种光隔离器,实现光波正向传播、反向隔离,解决了背景技术基于法拉第旋转式原理制得的光隔离器存在的技术问题。本发明是利用光路系统中起偏器产生线偏振光,磁旋光玻璃的非互易圆双折射特性以及自然旋光晶体的互易性圆双折射作用,使正向光能够重新聚焦在输出端,而反射回的光在通过磁旋光楔形玻璃之后不能在正向输入端聚焦而被隔离,从而达到光单向传输的目的。本发明具有反向光隔离度高、插入损耗低 ...

开口隔离层上多晶硅薄膜制备

open access: yes, 2006
在SSP硅带衬底上制备开口SiO2隔离层,在隔离层上沉积多晶硅薄膜籽晶层;然后以ZMR将制备的多晶硅薄膜区融、进行再结晶,制备了SSP隔离层上多晶硅薄膜,并制备了多晶硅薄膜电池.研究结果表明:ZMR对籽晶层的区融、结晶效果比较理想,晶粒尺寸增大到厘米级长、毫米级宽;经过晶硅薄膜沉积后,开口隔离层的孔洞未完全被多晶硅薄膜层覆盖住;制备的电池的光特性参数Voc、Isc、FF都比较低,电池的最高转换效率为3.83 ...

肝脏分隔及门静脉右支结扎术后肝内门静脉侧支血管开放与肝组织增生关联分析 [PDF]

open access: yes, 2022
目的探讨肝实质分隔和门静脉右支结扎术后肝内门静脉侧支血管开放对残余肝组织增生水平的影响。方法回顾性分析2013年4月至2022年6月在中山大学附属第一医院行肝实质分隔和门静脉右支结扎术的肝细胞癌患者的临床资料。根据患者一期术后肝内门静脉开放侧支血管的数量分为3组:未开放组,开放血管1条组和开放血管≥2条组。首先分析3组在术前、术中及术后肝功能、肝组织增生情况、二期手术情况等方面的分布差异,进一步采用多重线性回归分析探讨影响一期术后肝内门静脉开放侧支血管数量不同的因素 ...
